IMPORTANT: You should understand the implications of changing a
group's path or name. For more information, see Renaming Users and
Groups in the Using IAM guide.

NOTE:To change a group name the requester must have appropriate
permissions on both the source object and the target object. For
example, to change Managers to MGRs, the entity making the request
must have permission on Managers and MGRs, or must have permission on
all (*). For more information about permissions, see Permissions and
Policies.
